Garrett Motion Inc.

A maker of turbochargers that help car and truck engines squeeze more power out of less fuel. Garrett's turbos are found on everything from everyday passenger vehicles to heavy-duty trucks and even race cars. The business traces back to engineer Cliff Garrett, who founded an aviation supply company in 1936 that began building turbochargers in the 1950s, even making one for the first turbocharged passenger car in 1962. After decades as part of Honeywell, Garrett became its own company again in 2018, keeping the founder's name alive.
